A method for controlling movement of an elevator car includes driving the car vertically to a landing; activating a park brake; and holding the car immovable with the park brake. The holding includes compressing a guide rail by compression members with a first compression force; opening a door for allowing loading and/or unloading the car; maintaining the door open for allowing loading and/or unloading the car while the car is held immovable; and starting closing movement of the door. After the starting closing movement of the door, relieving the brake for allowing the elevator car to start to move vertically. The relieving includes reducing the compression force of the brake, to be smaller than the first compression force, such that the compression members start sliding vertically against the guide rail; maintaining compression with a smaller compression force than the first compression force, allowing the compression members to continue to slide vertically against the guide rail; and thereafter removing the compression.

An elevator system includes a hoistway and an elevator car positioned in the hoistway and configured to travel along the hoistway. The elevator car includes an elevator car door. A door operator assembly is fixed in the hoistway at a landing floor and includes a sensor to sense presence of the elevator car at the landing floor; and a door operator mechanism to open both the elevator car door and a landing floor door when the sensor senses presence of the elevator car at the landing floor. A light source may be fixed at the hoistway and a light transmitter is positioned at the elevator car to gather light from the light source and output the light into an interior of the elevator car. A ventilation system may be fixed at the hoistway and is interactive with the elevator car to condition an interior of the elevator car.

A safety exit assembly for an elevator car and an elevator system. The safety exit assembly includes: a door panel, which is configured to open and close a safety exit of the elevator car, and which has an upper surface and a lower surface; a moving assembly, which includes a guide block provided on a lower surface of the door panel, and a guide rail which guides the door panel to move downward and translate through a cooperation with the guide block; a drive assembly, which drives the door panel to reciprocate along the guide rail; and a locking assembly, which includes an unlocking element provided on an upper surface of the door panel; wherein the unlocking element is electrically connected to the drive assembly, and an unlocking action of the unlocking element triggers the drive assembly to drive the door panel to move until the safety exit is opened.

A method of monitoring a door of an elevator car within an elevator system including: detecting a first plurality of accelerations along an X-axis of the elevator system during a first time period; detecting a second plurality of accelerations along a Y-axis of the elevator system during the first time period; determining an absolute value of the first plurality of accelerations; determining an absolute value of the second plurality of accelerations; determining a first summation of the absolute value of the first plurality of accelerations and the absolute value of the second plurality of accelerations; and determining whether the door of the elevator car is in motion during the first time period by determining whether a maximum value of the first summation is greater than a threshold value.

A method for monitoring thresholds for performance attributes in an elevator system is provided. Aspects includes collecting, by a sensor affixed to an elevator car, sensor data associated with the elevator system wherein the sensor data comprises one or more performance attribute values for a set of performance attributes of the elevator system. Obtaining a threshold profile associated with the elevator system, wherein the threshold profile comprises thresholds for each performance attribute in the set of performance attributes of the elevator system. Comparing the one or more performance attribute values to corresponding thresholds for the set of performance attributes and transmitting an alert for any of the one or more performance attribute values exceeding the corresponding thresholds for the set of performance attributes.

An elevator system includes a hoistway (217) including a landing (225A-225C), which includes a landing door (227A-227C), an elevator car (203), comprising an elevator car door (229), arranged to move within the hoistway (217), a first safety switch (231; 233) configured to indicate a potential hazard in the elevator system (201) and a controller (215). The controller (215) is configured, when the first safety switch (231; 233) is triggered, to stop movement of the elevator car (203) and determine whether the elevator car (203) is located anywhere within an unlocking zone (253) in the hoistway. The controller is further configured, if it is determined that the elevator car (203) is located anywhere in the unlocking zone (253), to allow the elevator car door (229) and landing door (227A-227C) to be opened.

An access door arrangement of an elevator shaft, wherein at least one elevator car is moving, includes a door lock, whereby in connection with the door lock a reset switch of an inspection mode resetting device is located, whereby the door lock has a lock part movable between a lock position and an open position and whereby the reset switch is integrated in said door lock to be operated by the movement of the movable lock part or a related movable part. This solution allows an easy resetting of the inspection mode of the elevator.

An elevator system has a rail system and a shaft door assembly on each of a plurality of floors of a building. The rail system has an electrically conductive guide rail that extends along the plurality of floors and guides a vertically movable component of the elevator system, and an electrically conductive bracket on each of the floors anchoring the guide rail to a wall of the building. The guide rail is electrically conductively connected to each of the brackets. Each shaft door assembly has a movable shaft door for openable closing of a shaft opening of the floor and an associated control device and/or drive device for moving the shaft door; wherein the control device and/or drive device is supplied with electrical energy via two electrically conductive paths with a first of the electrically conductive paths being formed over at least parts of the rail system.
